First, Sweden. Whether Rob, or you, or anyone is welcomed to migrate to any country should be at the discretion of the members of that country. I think that if Rob spoke Swedish, and German, and he had a large sum of funds deposited at a bank in Sweden, and he had studied Swedish culture and was equipped to assimilate into Swedish society, he would stand a better chance of being accepted into that country. He also would stand a better chance of contributing to that country economically once being accepted. He would likely create less social tension among the Swedes, who would respect him for his desire to uphold their traditions. I believe Rob has children. Let us assume that he does. Given Rob's commitment to his new status as a resident of Sweden, and his long track record of alignment with Swedish societal and cultural norms, Rob's children will, in turn, be very likely to hold less resentment against Sweden for any shortcomings they are faced with, as Rob leads by example and is a good steward of how one should respect the Swedes and appreciate the Swede's acceptance into their country. Lastly, on the topic of Sweden, Sweden is rather socialist. I will turn this now onto myself. If I were to ever move to Sweden, I would not expect the school system to modify their curriculum to account for my child's enrollment whatsoever. The Swedes pay a lot in taxes, and those taxes should go to services that best serve their Swedish communities.
Keeping it personal, I speak a foreign language. The language I speak is that of a country with strong tradition and a points-based immigration system. I believe such a system is the best way to ensure that those who are accepted into the country are of a mindset and a capability so as to contribute to the society of that nation in a fruitful manner. I don't speak Swedish, and if I were to be denied immigration to Sweden I would suggest that those who had been granted acceptance were not in fact better than me, they were better equipped. And I am better equipped for the country for which the language I speak.
I agree that there is fear and protectionism at the core for most, and elitism for some, but I do not ascribe any of those traits to another individual without just cause. The reasons for which any individual derives their beliefs is complex and nuanced.
